I've been there because they are affiliated with Woodcraft and had somethings that the Springfield story didn't have. Didn't go into the shop just the store. At one time I had considered getting a membership just for the hands on before I invested into this hobby. Changed my mind because the trip to Rockville is tough from where I'm at. If you live close and don't have the room or just want some hands on with other WWers might not be a bad deal.
BTW Jay adding your location might be helpful to everyone.
